Half way there... This is a 2x2x1 unit cell piece. It will look more geometrically robust with the next layers... I am not planning this model to have the typical #Quartz outer shape because I am just learning to connect the tetrahedra, but I am hoping the 2nd model will 🤞🏻

I can’t think of a more appropriate ending for the 10th Anniversary of #MinCup than Quartz winning, the mineral that started it all! Thank you to @mikamckinnon.bsky.social and the team for all the tireless work you do! The ballot stuffers can stuff it, though!

Update: I had to back up with my model cause the complexity of what I had done was not allowing me to figure out how to continue. After exploring a VESTA view of 8 unit cells for ~15 min I figured out a simple relation among lines of tetrahedra, so I already made enough lines and will connect them.

In order to celebrate #Quartz' victory in #MinCup26 a 3D model is in the making (promised during round 1). It gets more complex by the unit and failing one connection will make it glass 😖. At this point very careful steps are being taken so progress is slow. Hopefully I will finish it on Sunday! 🤞🏻

Things that make me laugh: Every time #Quartz has been in the #MinCup finals, it’s been against a mineral with the composition X₂O. This is particularly funny as ice and #Cuprite are the only two minerals with this composition, & ice took #MinCup19. Win some, lose some? Or history repeats?

It doesn't take much editing to make xkcd 2501 about #MinCup. marshdeer.github.io/xkcd2501-gen...
Custom variant of xkcd comic 2501: Average Familiarity.

[Ponytail and Cueball are talking. Ponytail has her hand raised, palm up, towards Cueball.]
Ponytail: Minerals are second nature to us MinCup fans, so it's easy to forget that the average person probably only knows graphite and halite.
Cueball: And quartz, of course.
Ponytail: Of course.
[Caption below the panel]
Even when they're trying to compensate for it, experts in anything wildly overestimate the average person's familiarity with their field.

Ten years after Mineral Cup began, the mineral that began it all, quartz, is into the semi finals. Quartz is the most common SiO2 polymorph, but there are 8 other known polymorphs of SiO2 (cristobalite, tridymite, coesite, lechatelierite, moganite, seifertite, stishovite and xiexiandeite).

Text:
Both quartz and graphite can form in the same kinds of rocks, either entangled together or with graphite as an inclusion within quartz. This gradient most often in hydrothermal fluid. As the fluids cool, carbon precipitates out first as graphite with silica crystallizing into clear quartz crystals around it.

I voted quartz, graphite is an interesting and useful mineral, but quartz is both a beautiful crystal form in varied colours, and a major component of rocks (igneous and sedimentary), also beaches, dunes and heaths. Piezoelectric properties are cool.
